Container Sealing Device

ABSTRACT

The utility model can be used in food industry and it is designated for storage and/or transportation of containers filled with low-viscosity and normal-density fluids. 
     The technical result of the present device is the improvement of the locking properties of the sealing ring of the stoppered container and the ability to use specific tamper-proof closures that need protection from overtwisting on the first unstopping and that contain both elements of fixation with the sealing ring collar of the stoppered container and a threaded joint. 
     The above-mentioned technical result is achieved by introducing unidirectional hooks on the preform sealing ring or on the ready-made container sealing ring, namely the flanges must be placed on the side face of the sealing ring below the thread. Also, the technical result is partially achieved by the presence of the thread itself.

TECHNICAL FIELD

The invention relates to sealing devices for containers.

BACKGROUND

The standard GOST R 10117.2-2002 has been applied as the nearestanalogue that regulates the design of containers and container sealingrings.

The majority of modern closures have some sort of a tamper-evidentindicator. This can consist of several elements, sometimes it is aone-piece unit, and however the general tendency clearly observed is toproduce a closure that is inexpensive, simple and tamper-proof. For thispurpose it is considered reasonable to introduce into the sealing systemthe elements of a preformed or a ready-made container sealing ring.

SUMMARY

The utility model can be used in food industry and it is designated forstorage and/or transportation of containers filled with low-viscosityand normal-density fluids.

The technical result of the present device is the improvement of thelocking properties of the sealing ring of the stoppered container andthe ability to use specific tamper-proof closures that need protectionfrom overtwisting on the first unstopping and that contain both elementsof fixation with the sealing ring collar of the stoppered container anda threaded joint.

The above-mentioned technical result is achieved by introducingunidirectional hooks on the preform sealing ring or on the ready-madecontainer sealing ring, namely the flanges must be placed on the sideface of the sealing ring below the thread. Also, the technical result ispartially achieved by the presence of the thread itself.

DESCRIPTION

The utility model can be used in food and household cleaning productsindustry and it is designated for storage and/or transportation ofcontainers filled with low-viscosity and normal-density fluids.

In the GOST standard, there are outlined technical solutions of which wehave chosen a container sealing ring with a threaded joint and a collar,except that the aforesaid sealing ring does not contain any elementsthat prevent overtwisting a portion of the closure or the closure in thewhole.

In particular, in the light of the mentioned above, we find it expedientto produce a sealing ring with unidirectional hooks as in a ratchetmechanism that would interact with the elements of the closure.

The technical result of the present device is the improvement of thelocking properties of the sealing ring of the stoppered container andthe ability to use specific tamper-proof closures that need protectionfrom overtwisting when unstopping for the first time and that containboth elements of fixation with the sealing ring collar of the stopperedcontainer and a threaded joint.

The above-mentioned technical result is achieved by introducingunidirectional hooks on the preform sealing ring or on the ready-madecontainer sealing ring, namely the flanges must be placed on the side ofthe sealing ring between the thread and the projection encircling thesealing ring. Also, the technical result is partially achieved by thepresence of the thread itself.

Placing unidirectional hooks on the side face of the sealing ringcontaining the thread is determined by the necessity to use specifictamper-proof closures that have additional elements of fixation with thecontainer sealing ring for the protection of the closure fromovertwisting when unstopping, that are also designed in the form ofunidirectional hooks interacting with the hooks of the sealing ring asin a ratchet mechanism.

The necessity of the thread on the container sealing ring is alsodetermined by the properties of specific types of closures, namelythreaded closures that allow interaction with the container.

Thus, the combination of unidirectional hooks on the sealing ring andthe thread on the portion of the sealing ring above the projectionencircling the ring (the ring collar) and respectively below the threadallows using tamper-proof closures with threaded joints and withelements of fixation with the collar of the stoppered container and alsoconsiderably improves securing the closure on the sealing ring of thecontainer.

Also, the projection encircling the ring (collar) is flattened and hasfabrication holes necessary for casting one-directional flanges. Thedevice is graphically illustrated, FIG. 1 demonstrating the generallayout of the device. The positions on the drawings indicate: containersealing ring 1, unidirectional hooks 2, projection encircling the ring(collar) 3, sealing ring thread 4.

The operation of the device can be characterized as follows: a closurewith the threaded joint and fixation elements is placed on the bottlesealing ring interacting with the sealing ring thread while the fixationelements of the closure, when having been pressed on, interact with theunidirectional hooks of the preform or container sealing ring. Thus,there is formed a reliable connection of the tamper-proof closure withthe stoppered bottle. When unstopping the bottle, the lockingunidirectional hooks of the sealing ring prevent axial rotation of theclosure indicator element or of the closure in whole that hascomplementary and unidirectional hooks that limit rotation of theclosure or its elements to one direction on further unstopping, theinteracting threads of the bottle sealing ring and of the closure resultin axial deflection of the device. The bottle is considered opened.

1. A bottle sealing ring characterized by the presence of thread and anencircling projection, in addition to which on the lateral outer surfaceof the sealing ring there are added unidirectional hooks, locatedbetween the encircling projection and the thread of the sealing ring,that interact with the mating teeth of the closure or its elements as ina ratchet mechanism.
 2. The preform or bottle sealing ringabovementioned in the clause 1, with the difference that the encirclingprojection is flattened and has holes.
